COLUMNS INTERNALS AND PACKING

Columns internal and graphite random packing

Mersen supplies various internals made of Graphilor®3, Fluoropolymer (PTFE, PVDF), metals in massive (tantalum, titanium, hastelloy, zirconium) or CL-Clad® (tantalum).

Column internals or accessories:

• Hold-down grids
  
• Spargers
  
• Liquid distributors, liquid re-distributors
  
• Special pipes

Graphite random packing:

• Raschig rings
  

Material expertise:

Mersen's internals and accessories are a complementary offer to the columns. Our corrosion-resistant materials are used in the manufacture of internals and accessories.

⇒ GRAPHILOR® 3 IS THE ONLY IMPREGNATED GRAPHITE RESULTING FROM THE COMBINATION BETWEEN ISOSTATIC GRAPHITE AND A SPECIFIC RESIN.

Mersen offers a range of three Graphilor® 3, based on various impregnants (phenolic, carbon and PTFE) which ensure the imperviousness, the resistance to corrosion and temperature as well as the long-term stability.

⇒ CL-CLAD® IS A PATENTED BRAZING PROCESS DEVELOPED BY MERSEN.

In this process, a thin layer of reactive metal (tantalum) can be cladded onto a carbon steel or stainless steel base plate. CL-Clad® technology is perfectly suitable for large thickness when design pressure is high.

This new process offers an excellent resistance to thermal and mechanical shocks, a full vacuum resistance and a superior corrosion resistance against most process fluids.

⇒ ARMYLOR® PTFE IS MERSEN MATERIAL MADE FROM PTFE OR PFA.

Our expertise is the mastering of all PTFE manufacturing processes, such as paste extrusion process, isostatic molding and PFA transfer molding.
